Are FlyBE xenophobic?

We suffered at the hands of another "Fly mayBE" mishap today. Our plane was cancelled due to "operational reasons" following fog. Fair enough, perhaps, except that why was it only the international flights (Dublin, France, Channel Islands (semi-International)) that were cancelled, when everyone else - most of whom could have got a bus/train instead - got to fly (albeit late)? Why do FlyBE have it in for their foreign passengers? Or do they simple have a strange policy where the more inconvenient a cancellation will be, the more likely it is to occur?

A mystery. My advice, though: avoid FlyBE unless you have no other option. They are very unreliable and seem to have very poor contingency plans for when things go wrong. Which, in my experience with them over the past year, they do quite often!
